4 Claims. (Cl. 57-130) tion which is well adapted for use with theselonger and heavier yarn packages, and which is strongly resistant toaccidental deformation, particularly during the dofiing operation.

A further object of the invention is to provide an improved spindlewhich may be manufactured at a substantially reduced cost.

My invention further relates to arrangements and combinations of partswhich will be hereinafter descrlbed'and more particularly pointed out inthe appended claims.

Preferred forms of the invention are shown in the drawings, in whichFig. 1 is a side elevation of one form of my improved spindle, with thespindle rail and yarn tube shown in'section; v

Fig. 2 is a sectional side elevation of certain parts shown in Fig. 1;

Fig. 3 is a partial sectional elevation show-' ing a modification; andt1F'ig. 4 is a similar view of a further modificaon. v

Referring to the drawings, I have shown a spindle adapted for use in aspinning or twisting machine and comprising a base III which may be secured in a ring rail or other supporting structure II by a clamping nutl2. The base may be provided with the usual oil tube II and dofier guardi5.

The rotating "element of my improvedspindle comprises a blade 20, abarrel 2| and a driving recessed at 24 to receive the tapered upper endportion 25 of the blade 20. The blade has the usual bearing support inthe base III and is commonly formed of hardened steel. The barrel is offull size to its extreme lower end,

. 2 Thewhirl 22 has an upwardly extendingsleeve portion 28 which isfirmly fitted about the fullsize lower end of the barrel 2 I. The whirl22 and sleeve 28 are preferably integral and formed of steel. The sleevereeniorces and strengthens the recessed lower. end portion of the barreland loosely centers the lower end of the tube T. The

.upper edge of the sleeve 28 is outwardly and downwardly beveledtoiacilitate the placing of yarn tubes thereon.

In the preferred manner of assembling the parts, the sleeve 281s pressedon to the recessed lower end of the barrel 2| before the recess isfinished and reamed. These latter operations are then performed afterthe parts 28 and 2| are assembled.v The upper end portion of the blade20 is then pressed firmly into the recess 24, completing the assembly. 7

When the tube T is mounted on the spindle, the lower end of the tubepreferably has a slight clearance relative to the sleeve 28, asindicated at B in Fig. 1.

As the sleeve 28 is of greater outside diameter than the lower end ofthe barrel 2|, the sleeve 28 holds the lower end of the tube T out ofcontact with the barrel 2|.

In the form of the invention shown in Fig. 3, the construction is aspreviously described with reference to Figs. 1 and 2, except that theupper end of the barrel 2la is provided with a wearreslstant cap orshell 30. This cap protects the relatively soft and light metal whichforms the barrel 2|a from wear and from injury during the dofilngoperation. Such protection is of substantial importance, due to thelarge size and relatively heavy weight of the yarn packages.

A further modification of my invention is shown in Fig. 4, in which thesolid light-weight barrel 2| is replaced by a thin steel tube which isclosely fitted outside of a filler piece or bushing 4| which in turn isseated on the tapered upper end 42 of the blade 44. An upwardlyextending sleeve 45 firmly encloses the lower end ofthe tube 40 and isassociated with the driving whirl, as in Fig. 2.

A plug is inserted in the open upper end of the tube 40 to close theopening and to prevent the accumulation of lint and dirt therein.

The plug 50 is smoothly rounded and has its outer surface aligned with"the outer surface of the sleeve 40. The plug may be of any suitablematerial and is preferably recessed as indicated in dotted lines at 52to reduce weight.

The construction shown in Fig. 4 has many of the advantages of theconstructions shown in l'ig altoaandtheuseotsteeltubingproridesincreased strength and stiflness.

The modified construction shown in Pig. 4 is not claimed. specificallyherein but forms the subject matter of divisional application Serial No.165,910, filed June-3, 1950.

Havingjthus described my invention and the advantages thereof. 1 do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

1'. In a spindle for supporting and rotating a yarn carrier, a one-piecesteel blade havin an enlarged upper end portion, a barrel oi alightweight material which carries its full diameterto its extreme lowerend and which has a recess'in its lower end portion in which'theenlarged upper end portion of said blade is received and firmly engagedand which enga es and centers said yarn carrier at its upper endonly,and a driving whirl oi a strong metal which has an upwardly-extendedsleeve which encircles and firmly engages the lower end portion of saidbarrel on its full-size outer surface, and which is of greater outsidediameter than said barrel, whereby said upwardly-extended sleevereeniorces said barrel and loosely centers the, lower end portion ofsaid yarn carrier and holds said lower end portion spaced outwardly fromsaid"- barrel.

-2. The combination in a spindle i'or supporting and rotating a yarncarrier as set torthin claim 1, in which the barrel is oi relativelysoft metal, and in which a wear-resistant metal en-,

. 4 circling member protects the upper end of said barrel 3. Thecombination in a spindle iorsupportingandrotatingayarncarrierassettorthin claim 1, in which thebarrel is or relatively soft metal. and in which an inverted hollow capof wear-resistant metal is mounted on and protects the upper end of saidbarrel.

4. The combination in asplndle for supporting and rotating a yarncarrier as set forth in claim 1, in which the barrel is of relativelysoft metal, and in which an inverted hollow cap of wear-resistant metalis mounted on and protects the upper end of said barrel. and in whichthe outer side surface or said cap is continuously aligned with theouter cylindrical surface of said barrel.
